ABSTRACT:
A light trigger thyristor including a light guide (30) held in a receiving metal fitting (11) with a light entering end side of the light guide (30) inserted into one end of a cylindrical sleeve (15). A plano-convex lens (17) is inserted into the other end of the cylindrical sleeve (15) to face a light introducing window (LW). A connector terminal (12) to which step index optical fibers (131, 132) are connected is attached to the metal receiving fitting (11). The light triggering thyristor prevents light from leaking out a bending portion of the light guide (30) to increase the transmission efficiency of light signals, prevents breakdown of the thyristor element due to concentration of the light signals even when light signals entering the light guide (30) are provided through a plurality of optical fibers from a plurality of light sources, and decreases optical loss due to misalignment of the optical axis of the optical transmission system without requiring very accurate adjustment to the relative position of the optical fibers (131, 132) and the light guide (30).
